I applaud Tim Harper’s column for characterizing climate change as it should be: “so alarming that it simply cannot be ignored.” It is baffling that the Harper government and the Canadian public continue to pretend that we can afford to do nothing about this enormous problem. Authoritative reports like The National Climate Assessment are simply confirming what we have known for years. Climate change is already happening, it is caused largely by human-induced carbon emissions, and the longer we wait to address it, the more costly it will be. With unusually extreme weather happening more frequently both here at home and around the world, it is articles like this one that will help Canadians to connect the dots and shake out of their slumber on climate change.
